PHILIP MUELLER, OF DECATUR, ILLINOIS;

. To all whom it may concern:

Be it known that I, PHILIP MUELLER, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Sanitary Drinking-Fountains, of which the following is a specification. 1

The present invention relates to sanitary drinking fountains of that type in which a, bubbler head is provided from which, when the valve is operated, a drinking streamer jet is projected to a point above the bubbler head convenient for drinking, andthe user will not be likely to bring his mouth in contact with the bubbler head.

In order, however, to further guard against possible touching of the lips to the bubbler head and increase the sanitary features of these devices, I have provided a guard so plaeed with respect to the orifice from. which the drinking stream issues that the user cannot in the ordinary'position of drinking place the mouth in contact with the head, and furthermore, this fountain is so designed thattheuseris protected from splashing or drip, and the entire structure is so designed that all objectionable crevices are eliminatechthe lodgment of contaminating matter guarded against, and, finally a thorough and efi'ective wash of all of the parts is secured by the construction which I have devised.

In the drawings herewith I have shown one embodiment of my invention, and in said drawings,

Figure 1 is a plan view of a fixture provided with my improved head.

several views, 10 indicates the supply fitting which may be of any suitable type, for it will be understood that the present invention is applicable to supply fittings of any design and other than that shown. The fitting lOis provided with a valve and valve operating means, as handle 11, by which the flow of the drinking stream is controlled.

;The supply pipe 10 isprovided at its de livery end with a fitting 12 having a vertical delivery'passage 13 therein, and havin as well, suitable means for securing the limbbler head in place, these means in the present instance comprising lugs 14 which engage ofi'set openings 15 in the bottom of the bubbler head, as shown in' Fig. 4, so that the lugsl l on the upstanding neck 16 of the fitting 12 will enter these apertures and by giving the parts a quarter turn the lugs 14 will engage a groove 17 in the bubbler head and secure the parts firmly together, any suitable cement or binder being used to give a tight joint.

The bubbler head 18 is preferably, though not necessarily, formed of vitreous material, as, for example, porcelain, and is preferably spherical in form so as to give a smooth, unbroken surface without crevices therein, although it may bevaried as to form to a considerable degree, the main desideratum being that the head resent a smooth, unbroken surface devoid of sharp angles and crevices. Projecting outwardly andv upwardly from one side of the head 18 is the guard 19, substantially in the form of a half cup, this shell 19 being placed on that side of the bubbler head 18 from which the fountain is used, so as toprovide a guard which will prevent the user bringing the mouth in contact with the head 18, and, furthermore, receive the waste and divert it away from the person drinking. The guard 19 joins the head 18 by smoothcurved joints, there being no interstices for the lodgment and retention of contaminating matter, and the top or rim 20 of the guard 19 is smoothly rounded, and its juncture with the guard 19 is by means of smooth, unbroken curves, so that all sharp angles tending to form crevices are eliminated. The guard 19 is referably connected to the surface of the cad 18 at a point above a horizontal plane passing throu h the center of the head.

It will e observed that the top or rim 20 of the guard 19 is bulged or enlarged somewhat sothat it is thicker than the wall of the guard 19, as shown in Figs. 3, 7 and 8, and that its ends 21 project overand beyond the edge of the guard wall 19, this edge 22 curving downwardly and. slightlyu-rear wardly to the body 18, all of these sections joining each; other {on ,smooth, unbroken curves so as to eliminate any sharp angles or crevices.

'lhisconstruction in use produces the action of the water which is ;grapli'icfally" illustrated in Figs, '7' and 8. The strea'nirises to the "desired -o f-., regulated height frorn thei jet Orifice I to point above the rin'i conyjen ent to the drinker, who may drink wlthout,

however, being able to bring the lips to'the jet orifice.- The/waste water falling flow ver the headlS which,"be1 ng formed on a smooth, unbroken curve, willldi'rec't the course,' follow the" curve of the head: 18

Owing to ,the curyed construction andfsmootli joints' r-of all of the parts no splashing will take place, but the flow will be srhoothjan d' unbroken with the final waste directed downwardly overlthe wallof the head 18, its curyed wall leading the wate r', of course a-round it as it flows downwardly so as to consolidate it and bring/9 W s r m is poin e aly beneath the hea1d18 from which it will be delivered. p

The action: of 'thesstrearn in practice is illustrated in, and ,8, It rises as a bubble to the desired or regulated. height above the rim 20, so as to be coni efiielit to the drinker. The waste water falling will strike the spherioalisurface of'the head 18, as heretofore described, thoroughly cleansting it: 1 That portion of the waste which fa-lls onto the spherical surfaceof the head fadjacent: the half cup or guard l9 wil l flow upwardly in a complete cleansing sheet, as

hereinbefere -(:le'scribed, namely, to the rim 20, and will then flow outwardly around the ends 22 of the uard 19, andcontinu ing around the outer surface thereof until it joins centrally, :flow's downwardly to any suitable waste trap or" receptaclep V obvious that by this" construction the user'will be protected" against any outward spla'shingof' the stream by the guard 19, but at the same time'the waste is so turned and -dir ected a's that an effective washing-of the head and guard is secured. Itwillbe seen that the construction is such thatno crevices" of angles exist for lodgment' of matter on the head, and,-furtliermore, that there is a moving sheet of water at all time'sfoy'er' and aboutth e parts, and that no opportunity er'iists for the, collection or standing of any water which falls from; the bubble; the" (5011813111051011' being 'such that a constant and natural:drainagev of water occurs. p e, v 1
